Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning devices, specifically relating to a reverse osmosis chemical cleaning device. Background Technology

[0002] Reverse osmosis (RO) technology, as a core process in water treatment, has been widely applied in seawater desalination, industrial wastewater reuse, municipal drinking water purification, and food and beverage production due to its high efficiency in desalination and low energy consumption. However, RO membranes inevitably face fouling problems such as particulate matter clogging, organic matter adsorption, inorganic salt scaling, and microbial biofilm formation during long-term operation, leading to decreased water production, increased operating pressure, and even shortened membrane lifespan. Chemical cleaning is a key means of restoring membrane performance. By using targeted agents to dissolve pollutants and kill microorganisms, membrane performance can be restored to more than 90% of its initial state. However, traditional cleaning devices have significant limitations in terms of operating efficiency, safety, and automation. In static soaking mode, the residual cleaning solution on the membrane surface after soaking relies on natural convection to dry, which is time-consuming and prone to secondary pollution or agent crystallization clogging the flow channels. In terms of safety and environmental protection, the risk of leakage of strong acids, strong alkalis, and oxidants during manual dosing and membrane element transfer threatens the health of operators. Therefore, the inventors have proposed a reverse osmosis chemical cleaning device. Utility Model Content

[0005] (2) Technical solution

[0006] To solve the above-mentioned technical problems, this utility model provides a reverse osmosis chemical cleaning device, including a cleaning chamber, a drying chamber, and a top cover. The drying chamber is located above the cleaning chamber on one side. A fan is provided on the surface of the drying chamber facing the cleaning chamber, and multiple sets of fans are arranged in an array along the surface of the drying chamber. An inner sliding groove is vertically opened at the center of the surface of the drying chamber. An inner sliding rod protrudes from the surface of the top cover facing the inner sliding groove, and the end of the inner sliding rod is slidably installed inside the inner sliding groove. Multiple sets of fixing rings are provided below the top cover, and the fixing rings allow the reverse osmosis membrane core to pass through.

[0007] Preferably, a vertically arranged mounting rod is fixedly installed at the end of the upper cover away from the inner sliding rod, and multiple mounting plates are installed on the mounting rod.

[0013] (3) Beneficial effects

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This specific embodiment is a reverse osmosis chemical cleaning device, the structural schematic diagram of which is shown below. Figure 1 As shown, it includes a cleaning box 1, a drying box 8 and a top cover 4. The drying box 8 is located on one side above the cleaning box 1. A fan 6 is provided on the surface of the drying box 8 facing the cleaning box 1. Multiple sets of fans 6 are arranged in an array along the surface of the drying box 8.

[0028] Reference Figure 2 , Figure 4 The drying oven 8 has a vertically oriented inner groove 5 at the center of its surface. An inner sliding rod 13 protrudes from the surface of the top cover 4 facing the inner groove 5, with its end sliding inside the inner groove 5. A vertically oriented mounting rod 12 is fixedly mounted on the end of the top cover 4 away from the inner sliding rod 13, and multiple mounting plates 9 are mounted on the mounting rod 12. A drive motor 7 is fixedly mounted on the upper surface of the drying oven 8. An inner screw is connected to the output shaft of the drive motor 7, and the inner screw rotates vertically within the inner groove 5. The inner sliding rod 13 has threaded holes adapted to the inner screw. The side wall of the cleaning chamber 1 has spaced-apart inlet pipes 3 and outlet pipes 2.

[0029] Reference Figure 3 Multiple sets of fixing rings 11 are provided below the top cover 4, through which the reverse osmosis membrane core passes. The mounting plate 9 and the mounting rod 12 are detachably connected, and multiple spaced support rods 10 are fixedly connected to the mounting plate 9. The fixing rings 11 are spaced apart on the upper surface of the support rods 10, and the fixing rings 11 are fixedly connected to the support rods 10.

[0030] Working Principle: This reverse osmosis chemical cleaning device achieves efficient cleaning and operation through the coordinated design of mechanical structure and drying system. During operation, the reverse osmosis membrane core is inserted into multiple sets of fixing rings 11 below the upper cover 4 for positioning. Then, the drive motor 7 on the upper surface of the drying chamber 8 is activated. Its output shaft drives the inner screw to rotate in the inner sliding groove 5. The inner sliding rod 13, threaded with the inner screw, slides vertically along the inner sliding groove 5, thereby driving the upper cover 4 to move downwards as a whole. This allows the membrane core within the fixing rings 11 to be completely immersed in the chemical solution in the cleaning chamber 1 for static soaking. The chemical solution is injected through the inlet pipe and discharged through the outlet pipe 2 to achieve circulation and renewal. After soaking is complete... Then, the drive motor 7 reverses and lifts the top cover 4. At this time, multiple sets of fans 6 arranged in an array facing the cleaning box 1 in the drying box 8 start, forming a forced convection air field to directly blow on the membrane core surface, accelerating the evaporation of residual chemicals. This device replaces manual handling with an automated lifting mechanism, eliminating the risk of leakage of strong acids, strong alkalis and oxidants. At the same time, the forced air drying shortens the drying time to less than 1 / 10 of the traditional natural convection mode, effectively avoiding chemical crystallization that clogs the membrane pores or secondary growth of microorganisms. Combined with the modular installation structure, it can adapt to the batch processing of membrane cores of different sizes, significantly improving the safety and operation and maintenance efficiency of RO system chemical cleaning.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
